Solution

1. Preparation

Gather tools: multimeter, socket set, wire for bypassing starter, battery terminal cleaner, and safety gloves.
Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Inspection and Cleaning

Disconnect the negative battery terminal using a socket wrench.
Clean corrosion off the battery terminals using a battery terminal cleaner.
Reconnect the terminals tightly and check for any improvement in starting.

3. Starter Motor Testing

Locate the starter motor; consult the vehicle manual for exact location.
Remove the electrical connector from the starter motor.
Use a wire to connect the positive terminal directly from the battery to the starter motor’s terminal.
If the starter engages and the engine cranks, the starter motor needs replacement.

4. Replacement of Faulty Components

If the battery is found to be faulty, replace with a new battery of the correct specifications (typically 12V, group size as per Ford F-150 specifications).
If the starter motor is faulty, remove the starter by unbolting it from the engine and disconnecting the wiring harness.
Install the new starter motor by reversing the removal steps and ensuring all connections are secure.

5. Final Inspection

Reconnect the negative battery terminal.
Attempt to start the engine to verify the repair.
